Abstract

1. A radio network having portable transceivers which include an identification signal generator, for security personnel, and having a radio centre which is common to all radio sets and to which the identification signals produced in the identification signal generators of the radio sets are transmitted and which acknowledges the identification signal received, each identification signal comprising an identification code characteristic of the relevant radio set and an information code characteristic of the location of the identification signal transmission, and a coding device which is brought into engagement with the identification signal generator of the radio set at the location of the identification signal transmission for the purpose of forming the information code, characterised in that the identification signal generator is accommodated in a hand-held part which is spatially separated from the radio set and which is connected to the radio set by means of a cable.

State of the art

The invention is based on a radio network according to the preamble of the main claim.

So-called time clocks are known with which security personnel is equipped for property protection. The security guard has to go to an object to be monitored on his guard round predetermined locations, which are equipped with a code key, "stab" with the code key. If the code key is inserted into the time clock, then the predetermined location is registered on the security guard's time clock and together with the time running in the time clock on a strip of paper printed out. With the help of the time clock, it is possible to check whether the security guard is doing his guard round according to the regulations has gone. However, this method has the disadvantage that an inspection is only carried out after the guard round has passed can be carried out, so that there is a certain uncertainty during the guard round, since it cannot be determined where a security guard is at a questionable time, unless the security guard can be reached and interrogated by radio.

Advantages of the invention

The radio network according to the invention with the characterizing features of the main claim has the advantage that a security guard is on watch can be followed and checked at any time to determine whether the security guard on his guard round the corresponding

passes the checkpoints or whether the security guard may not go to a checkpoint.

Another advantage is that they have a coding device The identifier that can be entered is designed in such a way that the identifier cannot be manipulated in an improper manner.

Through the measures listed in the subclaims advantageous embodiments of the specified in the main claim Radio network achieved. It is particularly advantageous that the identifier in the first part of the information content is used as an identification code is trained for the security guard concerned.

According to the invention, additional equipment on the radio is for Security guards provided, whereby the possibility is created to constantly follow the guards during the guard walk and to recognize any irregularities immediately. Each security guard is with a handheld radio equipped, which contains a device for transmitting an identifier, for example a cqdbaren identifier. The identifier in the identifier is coded in a first part of its information content on the security guard concerned and contains a specific code in a second part of its information content. The specific code is on the control body, which the security guard starts up during his guard walk, can be coded by external measures. Preferably one takes place

such coding via a coding plug of a suitable design to be inserted or attached to the device from the outside. The coding can be done by mechanical contacts, by electron-optical scanning, by magnetic scanning or the like. For coding, the coding plug is inserted into the identifier or connected to it created the identifier. With the correct position of the Codior connector For example, a "contact" is actuated, which can be designed both mechanically and electronically, so that in this way the identification is sent out. The identifier is in the control center of the point network or in the Radio control center recorded and decoded in a corresponding device, for example in an identifier evaluator. Due to this process, the current location becomes known where the security guard is currently located. The incoming Information can be registered on a printer, for example, together with the time taken from a time source. In this way, the guard round that has passed can be checked immediately, so that any irregularities can be recognized immediately will.

In a further embodiment of the radio network according to the invention, the information about the individual guard rounds of a Each security guard can also be stored in a data processor, so that the time and the control point of the guard round be held. In addition, it is also possible to have different Save guard rounds and enter them manually

to expand the number of the corresponding security guard. the Incoming information is tracked and evaluated in the data processor. The evaluation can either be carried out on a Printer and / or take place in a suitable manner on a screen, for example in graphical representation.

According to the invention, every incoming information is acknowledged. In a simple process, the receipt can only be consist of a "beep" emitted by the radio center. However, if several security guards take the guard round go, can quickly misinterpretation when sending a beep, so that in an improved process according to the invention the acknowledgment is given by selective call only to a specific participant. In this case becomes the acknowledgment tone in the guards' portable handheld radios generated by selective call evaluation itself; "en.

The identifier can be arranged both in the radio device and in a small hand-held part that is connected to the radio device via a cable connected is. The handset can have the facilities required to carry out normal radio communication included, for example microphone, loudspeaker, send button and the like.
